Description

The invention relates to a device for the subsequent thermally insulating, force-transmitting connection of a second load-bearing structure part to a first load-bearing structure part, in particular a building ceiling and a balcony slab, and a structure with such a device.

From the DE 10 2005 012 862 A1 a construction element emerges that is used to connect two reinforced concrete components. An angle is provided on which one of the reinforced concrete components is supported, so that the connection device engages under the reinforced concrete component. Shear rods are fixed to the bracket. The sloping section of the shear force bars is arranged in the expansion joint between the structural parts. The transverse force bars protrude through openings in the rear wall of the bracket and are fixed to a support plate of the bracket. This results in a comparatively complex construction of the connecting device.

The present invention is based on the object of creating a device for the subsequent thermally insulating, force-transmitting connection of a second load-bearing structure part to a first load-bearing structure part, which has a simple structure and enables favorable transverse force transmission. A further object of the present invention consists in specifying an advantageous building with such a device.

With regard to the device for the subsequent thermally insulating, force-transmitting connection of a second load-bearing structure part to a first load-bearing structure part, this object is achieved by a device having the features of claim 1 . With regard to the building, the object is achieved by a building with the features of claim 14.

It is provided that a support angle is provided for the transmission of the compressive forces and transverse forces, which has a contact surface for transmitting the compressive forces and a contact surface for absorbing the vertical transverse forces. Due to the fact that the pressure forces and transverse forces are transmitted via a bearing surface and a bearing surface, subsequent assembly of the second part of the structure is possible in a simple manner by placing it on the bearing bracket. In order to achieve good introduction of the transverse forces, it is provided that the two legs of the support bracket are connected via at least one cheek arranged transversely to the longitudinal direction of the insulating body. The transverse force bar is fixed directly to the cheek with its inclined section running obliquely to the vertical direction. As a result, the transverse force bar protrudes with its sloping section beyond the contact surface in the direction of the second part of the structure. As a result, the transverse forces can be introduced at a comparatively large distance from the first part of the structure. At the same time, fixing the shear force bar to the stringer offers a simple and stable way of fixing it. At the same time, the cheek stabilizes the angle and enables the second structural part to be secured in position relative to the first structural part in the longitudinal direction of the insulating body. The cheek does not have to extend into the gusset of the support bracket, where the two legs of the support bracket meet, but can be recessed in the area of the gusset. The positioning of the second structural part on the first structural part during assembly of the second structural part as a finished part on the first structural part is possible in a simple manner.

The device is designed in such a way that it enables the second part of the structure to be subsequently connected to the first part of the structure. "Subsequently" means in this context that the first structural part and the second structural part can be manufactured separately from one another, in particular from concrete, and that the device is designed in such a way that it is possible to remove the structural parts after they have been manufactured, i.e. in particular after the Concrete of the building parts has become solid to connect with each other. A subsequent connection is not possible, for example, if a reinforcement part has to be embedded in the concrete of both parts of the structure.

It has been shown that it is advantageous for a good introduction of force if the distance between the end of the inclined section of the transverse force bar and the underside of the insulating body that faces away from the first longitudinal side is as small as possible. As a result, forces can be introduced approximately at the level of the underside of the insulator. The underside of the second structural part is usually arranged approximately level with the underside of the insulating body, so that the force can be introduced due to the specified arrangement near the underside of the second structural part. The distance, measured in the vertical direction, of the end of the inclined section of the transverse force bar arranged on the cheek and the underside of the insulating body is preferably less than 5 cm, in particular less than 2 cm. The other end of the sloping section is advantageously arranged in the insulating body, or the sloping section projects completely through the insulating body. Particularly in the case of comparatively high insulators, the distance between the end of the inclined section of the transverse force bar and the underside of the insulator can also be greater. Advantageously, the distance between the end of the section of the transverse force bar arranged on the cheek and the underside of the insulating body is at most a quarter of the height of the insulating body.

The end of the inclined section of the shear force rod that is arranged on the cheek and faces away from the first longitudinal side is preferably positioned at the greatest possible distance from the first part of the structure in order to enable a favorable introduction of force.

The end of the sloping section of the shear force bar that is arranged on the cheek and faces away from the first longitudinal side is advantageously at a distance from the insulating body, measured in the transverse direction, which is at least 2 cm, in particular at least 5 cm. The end of the inclined section of the shear force bar that is arranged on the cheek and faces away from the first longitudinal side is advantageously at a distance, measured in the transverse direction, of at least 2 cm, in particular at least 5 cm, from a rear side of the first leg that faces away from the second leg. If the support bracket is arranged on the second longitudinal side of the insulating body, the distance from the insulating body corresponds to the distance from the rear side of the first leg.

Advantageously, the distance measured in the vertical direction of the end of the inclined section of the shear force rod facing away from the first longitudinal side to the underside of the insulating body is smaller than the distance of this end to the insulating body measured in the transverse direction. The distance from this end to the underside of the insulating body, measured in the vertical direction, is preferably less than 80%, in particular less than 50%, of the distance from the end to the insulating body, measured in the transverse direction.

In a particularly advantageous embodiment, the inclined section of the transverse force bar is welded to the cheek. However, another type of attachment can also be provided.

An advantageous design results when two cheeks are arranged at opposite ends of the support bracket, on each of which a transverse force bar is fixed. This enables a good distribution of the introduced shear force to the two shear force bars and a symmetrical introduction of force.

The support bracket is advantageously made of metal. The support bracket, including the at least one cheek, is particularly preferably formed from sheet metal, in particular by stamping, bending and welding.

In a preferred embodiment, the support bracket protrudes beyond the insulating body in the direction of the second structural part. When viewed in the longitudinal direction, the support angle is advantageously at most partially overlapping with the insulating body. Particularly preferably, the support angle does not overlap with the insulating body when viewed in the longitudinal direction. In an alternative advantageous design, however, it can also be provided that the insulating body has a recess in which the support bracket is partially or completely arranged. This is particularly advantageous when a comparatively wide expansion joint has to be bridged.

Provision can be made for the second part of the structure to be supported directly with its concrete on the support bracket. For an improved introduction of force, it is provided in particular that the device comprises a support part, in particular a support bracket, which is provided for embedding in the second part of the structure. The support part advantageously has a first support surface for transmitting compressive forces directed in the transverse direction and a second support surface for transmitting transverse forces directed in the vertical direction to the support bracket. The support part can rest directly on the support bracket. However, the interposition of further elements between the supporting part and the support bracket can also be provided.

In order to enable good force transmission between the supporting part and the second structural part, at least one reinforcement element is advantageously fixed to the supporting part. The reinforcement element is preferably at least one compression bar, which is to be embedded in the concrete of the second part of the structure.

In order to enable the second structural part to be placed on the support bracket, it is advantageously provided that the second structural part has recesses for the cheeks of the support bracket. In order to make these cutouts in a simple way can, it is advantageously provided that the device comprises a formwork body which has at least one recess for receiving the at least one cheek and the section of the shear force rod arranged thereon. The formwork body is preferably intended to remain in the second structural part. However, it can also be provided that the shuttering body is removed from the second structural part before the second structural part is attached to the first structural part.

The formwork body advantageously has a first surface for support on the contact surface and a second surface for support on the support surface. The support part, in particular the support bracket, is advantageously supported on the formwork body, so that the force is transmitted between the parts of the building from the support part via the formwork body into the support bracket. If the shuttering body has two recesses, it is advantageously provided that the length of the support part measured in the longitudinal direction of the insulating body is smaller than the distance between the two recesses of the shuttering body. As a result, the support part can be positioned well on the formwork body. Particularly preferably, the length of the support part measured in the longitudinal direction of the insulating body is at most 1 cm less than the distance between the two recesses of the formwork body. The length of the support part advantageously corresponds to the distance between the two recesses minus twice the wall thickness of the formwork body.

The device includes tensile force-transmitting means for transmitting tensile forces between the two parts of the structure. Advantageously, the tensile force-transmitting means include first tension rods and second tension rods. The first tension rods are advantageously provided for embedding in the first part of the structure and the second tension rods for embedding in the second part of the structure. Advantageously, the first and second tension rods extend substantially on opposite sides of the insulating body. Advantageously, either the first tension rods or the second tension rods protrude through the insulating body. The first tension rods are advantageously connected to the second tension rods in a force-transmitting manner. The force-transmitting connection of the tension rods to one another is advantageous arranged outside of the insulator. In a particularly preferred embodiment, the first tension rods and the second tension rods are arranged in a common plane running perpendicular to the vertical direction. This enables advantageous power transmission.

A simple design results when the first tension rods and the second tension rods are fixed to a common connecting plate. The first and second tension rods can be connected to the connecting plate, for example, via screw connections or via welded connections. Preferably, at least the connection of the first tension rods or the connection of the second tension rods to the connection plate is detachable, so that subsequent connection of the second structural part to the first structural part is possible simply by attaching the second structural part and producing the screw connections. The second part of the structure can be manufactured entirely in the precast plant, and no in-situ concrete, injection mortar or the like is required on site to connect the second part of the structure, which is delivered in the finished state, to the first part of the structure.

For a structure it is provided that the structure has a first load-bearing structure part made of concrete and a second load-bearing structure part made of concrete as well as a device for connecting the second load-bearing structure part to the first load-bearing structure part. The insulating body of the device is arranged in a parting line between the first structural part and the second structural part. The first longitudinal side of the insulating body is arranged on the first structural part. The second part of the structure is supported on the contact surface and the bearing surface of the support bracket in relation to the first part of the structure. The section of the shear force bar that protrudes beyond the insulating body into the first part of the structure is embedded in the concrete of the first part of the structure. The building is advantageously produced by the second building part being produced in the precast plant, being positioned on the second building part on the construction site and being fixed to the first building part merely by connecting first and second tensile force-transmitting elements.

Advantageously, the support angle does not overlap with the insulating body when viewed in the longitudinal direction of the insulating body. The second structural part advantageously has at least one recess open to the underside and to the face of the second structural part, into which the at least one cheek of the support bracket protrudes.

First tension rods are advantageously embedded in the first structural part and second tension rods are embedded in the second structural part, which are connected to one another on a connecting plate arranged on one of the structural parts. The part of the structure that has the connecting plate advantageously has recesses adjacent to the connecting plate, in which recesses projecting from the other part of the structure through the insulating body and the connecting plate are screwed. The recesses are preferably arranged on the side of the connecting plate facing away from the other part of the structure, so that the tie rods can be fixed to the connecting plate by means of nuts placed and screwed onto the tie rods in the recesses. This results in a simple structure.

The tension rods of the device are preferably not connected to the compressive force-transmitting means and the transverse force-transmitting means, but are arranged separately from them. As a result, the height of the device can be easily adjusted by selecting an insulating body with the desired height or by assembling an insulating body from several elements until the corresponding desired height is reached, without further modifications to the force-transmitting elements being necessary. This achieves a simple and modular structure of the device.

1 12 schematically shows a section of a building 50. The building 50 has a first building part 2, in the exemplary embodiment a building ceiling, and a second building part 3, in the exemplary embodiment a balcony slab. The second structural part 3 is connected to the first structural part 2 via a thermally insulating component 1 in a thermally insulating and force-transmitting manner. The load-bearing parts of the structure 2 and 3 are made of concrete, in the exemplary embodiment made of steel-reinforced concrete. The load-bearing structural part 3 has been fixed to the first load-bearing structural part 2 after it has been produced. As a result, the load-bearing structural part 3 can be produced with high quality, for example in the prefabricated parts factory, and can be fixed very quickly to the structural part 2 on the construction site, which shortens crane times and thereby reduces production costs.

The thermally insulating component 1 comprises an insulating body 5 which is arranged in a parting line 4 between the first structural part 2 and the second structural part 3 . The insulating body 5 has a first longitudinal side 6 which is arranged on the first structural part 2 . The second, opposite longitudinal side 7 runs adjacent to the second structural part 3. In the exemplary embodiment, a narrow gap is formed between the insulating body 5 and the second structural part 3. However, it can also be provided that the second structural part 3 bears against the insulating body 5 .

The insulating body 5 has a longitudinal direction 28 which is aligned in the longitudinal direction of the expansion joint 4 . The longitudinal direction 28 preferably runs horizontally in the installed state. The insulating body 5 has a vertical direction 30 that runs perpendicular to the longitudinal direction 28 . The vertical direction 30 preferably runs vertically in the installed state. The insulating body 5 has a transverse direction 29 which runs from the first longitudinal side 6 to the opposite longitudinal side 7 . The transverse direction 29 is aligned perpendicularly to the longitudinal direction 28 and perpendicularly to the vertical direction 30 . The transverse direction 29 preferably runs horizontally in the installed state.

The thermally insulating component 1, together with other elements, forms a device for the force-transmitting connection of the second building part 3 to the first building part 2. The device consists of the thermally insulating component 1, which is fixed to the first building part 2, and other means arranged on the second building part 3 for power transmission. The force transmission means arranged on the second structure part 3 are advantageously detachably connected to the force transmission means arranged in the first structure part 2 . As a result, subsequent connection of the second structural part 3 to the first structural part 2 is possible.

For the transmission of tensile forces between the structural parts 2 and 3, the device comprises first tension rods 9, which are embedded in the first structural part 2, and second tension rods 10, which are embedded in the second structural part 3. The tension rods 9 and 10 are connected to one another in a force-transmitting manner. The force-transmitting connection of the tension rods 9 and 10 is provided outside of the insulating body 5 in the exemplary embodiment. In the embodiment after 1 the first tension rods 9 protrude through the insulating body 5 . Recesses 15 are provided on the upper side 40 of the second structural part 3 . The ends of the tension rods 9 protrude into these recesses 15 . As a result, the ends of the tension rods 9 are accessible from the top 40 . The second tension rods 10 are firmly connected to a connecting plate 11 arranged on the second structural part 3, in the exemplary embodiment via welded connections ( 2 ). The first tension rods 9 are screwed to the connecting plate 11 . For this is in the recesses 15 each have a fastening nut 14 screwed onto the tie rods 9 . In the exemplary embodiment, a disk 21 is arranged between the fastening nuts 14 and the connecting plate 11 . Because the recesses 15 are open on the upper side of the second structural part 3, the second structural part 3 can be placed with the connecting plate 11 on the tension rods 9 and fixed in a force-transmitting manner on the first structural part 2 by fixing the fastening nuts 14. The first tie rods 9 and the second tie rods 10 protrude from the connecting plate 11 on opposite sides.

A support bracket 17 is arranged on the second structural part 2 for the transmission of compressive forces and transverse forces. The support bracket 17 advantageously forms part of the thermally insulating component and is held captive in particular on the insulating body 5 . The support bracket 17 is firmly connected to transverse force bars 16 . The transverse force bars 16 are embedded in the concrete of the first structural part 2 and are thereby connected to the first structural part 2 in a force-transmitting manner. The support bracket 17 is supported in the horizontal direction on at least one compression bar 19 embedded in the first structural part 2 . Provision can be made for the support bracket 17 to be firmly connected to the at least one pressure rod 19 .

The first tension rods 9 have longitudinal axes 12 and the second tension rods 10 have longitudinal axes 13, as in FIG 2 is shown. As 1 shows, the first tie rods 9 and the second tie rods 10 are arranged at the same height. The longitudinal axes 12 and 13 lie in a common, horizontal plane 38. The plane 38 runs parallel to the longitudinal direction 28 and parallel to the transverse direction 29. The plane 38 runs perpendicular to the vertical direction 30. The tension rods 9 and 10 are offset from one another in the plane 38 arranged. As 2 shows, the longitudinal axes 12 and 13 of adjacent tension rods 9 and 10 measured in the longitudinal direction 28 offset a to each other.

The insulator 5 has a bottom 8, which is arranged below in the installed state, such as 1 indicates. The underside 8 runs approximately in one plane with an underside 45 of the support bracket 17 and an underside 46 of the second structural part 3.

the Figures 3 to 6 show the thermally insulating component 1 on the first structural part 2 in detail. The support bracket 17 of the thermally insulating component 1 has two legs 24 and 25 which are aligned at right angles to one another in the exemplary embodiment. The legs 24 and 25 run parallel to the longitudinal direction 28 of the insulating body 5. The first leg 24 runs parallel to the vertical direction 30. The first leg 24 is advantageously aligned vertically when installed on the building 50. On the side facing away from the insulating body 5, the first leg 24 forms a contact surface 22 for the transmission of compressive forces. The second leg 25 runs parallel to the transverse direction 29 and is advantageously aligned horizontally in the installed state. On the second leg 25, a bearing surface 23 for the transmission of transverse forces is formed on the side pointing upwards in the installed state. As the Figures 5 and 6 also show, the second leg 25 of the support bracket 17 runs close to the underside 8 of the insulating body 5. The second structural part 3 can be placed on the bearing surface 23 and then fixed to the first structural part 2.

The shear force rods 16 are embedded in the first structural part 2 and have a section 26 running at an incline to the vertical direction 30 and at an incline to the transverse direction 29 . In the installed state, the inclined section 26 drops from the first structural part 2 to the second structural part 3 . The inclined sections 26 of the two transverse force bars 16 run on the opposite outer sides of the cheeks 18. Each inclined section 26 is fixed directly to a cheek 18, in the exemplary embodiment by welding. The inclined section 26 of the at least one transverse force bar 16 protrudes through the insulating body 5.

The two legs 24 and 25 are connected to one another via at least one cheek 18, via two cheeks 18 in the exemplary embodiment. The cheeks 18 extend perpendicularly to the longitudinal direction 28. In the exemplary embodiment, the cheeks 18 are arranged on the two ends of the legs 23 and 24, which are arranged in the longitudinal direction 28. The at least one cheek 18 advantageously has an approximately triangular shape. The cheek 18 has an upper side 51 which connects the legs 24 and 25 . Preferably, the top 51 is in a straight line for at least a portion of its length. The upper side 51 of the cheek 18 advantageously runs in the viewing direction of the longitudinal axis 28 inclined to the transverse direction 29, preferably at an angle of 30° to 60°. The angle of inclination of the upper side 51 of the cheek 18 advantageously corresponds to the angle of inclination of the inclined section 26 of the transverse force bar 16.

In the exemplary embodiment shown, the support angle 17 is arranged outside of the insulating body 5 , specifically on the longitudinal side 7 of the insulating body facing away from the first longitudinal side 6 . The support bracket 17 thus protrudes into the area of the second structural part 3 . The pressure rods 19 are designed as comparatively long, straight rods that are embedded in the concrete of the first part 2 of the structure for the transmission of compressive force. The pressure rods 19 can be screwed to the support bracket 17, welded or attached in some other way.

As the Figures 3 to 6 also show, the straight sections of the transverse force bars 16 and the tensile force bars 9 run approximately at the same height in the first building part 2. This is also shown in 1 visible.

The design of the support bracket 17 and the reinforcement elements arranged thereon, namely the two transverse force bars 16 and the two pressure bars 19, is also shown in FIGS Figures 7 to 9 shown in detail. The support bracket 17 is advantageously made of metal. The support bracket 17 is in particular including the at least one Cheek 18 made of sheet metal, preferably formed from at least two sheet metal parts connected to one another.

As 10 1, the inclined portion 26 has an end 39. As shown in FIG. The end 39 is the end of the inclined section 26, which is arranged closer to the first longitudinal side 7 of the insulating body 5 than to the first longitudinal side 6. The other end of the inclined section 26 adjoins the straight section to be embedded in the first structural part 2 of the shear force bar 16, as well as the Figures 3 to 6 demonstrate. The end 39 has a distance f measured in the vertical direction 30 from the underside 8 of the insulating body 5 . The distance f is preferably comparatively small. The distance f is advantageously less than 5 cm, in particular less than 2 cm. The insulating body 5 has a height n measured in the vertical direction. The distance f is advantageously at most a quarter of the height n.

The first leg 24 of the support bracket 17 has a rear side 54 facing away from the second leg 25 . In the exemplary embodiment, the at least one compression bar 19 is fixed on the rear side 54 . In the exemplary embodiment, the end 39 has a distance g measured in the transverse direction 29 from the rear side 54 . The distance g is advantageously comparatively large. The distance g is advantageously more than 2 cm, preferably more than 5 cm. The distance f is preferably less than 80%, in particular less than 50%, of the distance g. The distance g from the back 54 corresponds to the distance of the end 39 from the insulating body 5 when the support bracket 17 is arranged with its back 54 on the second longitudinal side 7 of the insulating body 5 .

As 11 shows, the sloping sections 26 are welded to the cheeks 18 . The sections 26 are connected to the cheeks 18 via weld seams 27 . As 11 Also shown in FIG. 1, the cheeks 18 and leg 25 are formed from a single piece of sheet metal bent out of the plane of the leg 25 on opposite sides to form the cheeks 18. FIG. The first leg 24 is advantageous as separate plate formed and by means of an in 12 welded seam 44 shown connected to the cheeks 18 and the leg 25.

As 12 shows, the support bracket 17 has a vertical direction 30 ( 10 ) measured height h. The leg 18 advantageously extends over the entire height h of the support angle 17 measured in the vertical direction 30. The area of the section 26 running on the cheek 18 extends over a comparatively large proportion of the height h of the support angle 17. The inclined section 26 runs along of the leg 18 over a height i which is advantageously at least 50%, in particular at least 70%, of the height h. The free end 39 is at a distance k from the underside 45 of the support bracket 17 in the exemplary embodiment. However, it can also be provided that the end 39 projects as far as the underside 45 .

the Figures 13 and 14 show schematically the second structural part 3 with the elements for power transmission arranged thereon. The second tension rods 10 and the connecting plate 11 connected to the second tension rods 10 are provided in the second structural part 3 for the transmission of tensile forces. A support bracket 31 is provided for the transmission of pressure forces and transverse forces. Instead of the support bracket 31 provided in the exemplary embodiment, other types of support parts can also be provided for transmitting the horizontal compressive forces and the vertically directed transverse forces. Second pressure rods 20 are fixed to the support bracket 31 . The second pressure rods 20 are embedded in the second structural part 3 and are advantageously designed as straight rods. A different configuration of the second pressure rods 20 can also be advantageous. The support bracket 31 has a first support surface 32, which is aligned vertically in the installed state and is used to transmit horizontally directed compressive forces. The support bracket 31 also has a second support surface 33 . In the exemplary embodiment, the second support surface 33 is aligned perpendicular to the first support surface 32 . The second support surface 33 advantageously runs parallel to the Underside 46 of the second structural part 3 and parallel to the longitudinal axis 13 of the tension rods 10 ( 13 ).

In the exemplary embodiment, the support bracket 31 bears against a formwork body 34 . The formwork body 34 is preferably designed to be arranged on a formwork for the production of the second building part 3 and connects to the underside 46 and to the insulating body 5 (in the installed state). 1 ) facing end face 49 of the second structural part 3.

As 14 shows, two second pressure rods 20 are fixed to the support bracket 31 in the exemplary embodiment. The support bracket 31 has a length b that is parallel to the longitudinal direction 5 of the insulating body ( 1 ) is measured. The length b is measured in the horizontal direction when installed. the Figures 15 to 17 show the support bracket 31 and the formwork body 34 in detail. On its side facing the concrete of the second building part 3, the formwork body 34 has a 17 shown recording 47, in which the support bracket 31 is to be arranged. In the exemplary embodiment, the receptacle 47 is delimited by two recesses 37 arranged on the opposite side of the formwork body 34 . The two recesses 37 are at a distance c from one another that is greater than the length b of the support bracket 31 , so that the support bracket 31 can be positioned between the two recesses 37 . The formwork body 34 is preferably an injection molded part made of plastic.

As 16 shows, the shuttering body has a first surface 35 which is intended to rest against the contact surface 22 of the support bracket 17 and is used to transmit horizontally running pressure forces. As 13 shows, the shuttering body 34 has a second surface 36, which is designed to rest on the support surface 23 and is used for transverse force transmission.

The recesses 37 each have a width d. The width d of the recesses 37 is selected in such a way that a cheek 18 can be positioned in the recess 37 with the inclined section 26 of a transverse force bar 16 arranged thereon. The width d is selected in such a way that positioning is easily possible even with the usual building tolerances. As 11 shows, a cheek 18 and the inclined section 26 of the transverse force bar 16 arranged thereon have an overall width e. The width d of each recess 37 is greater than the overall width e. The width d is preferably only slightly larger than the total width e of the cheek 18 and the inclined section 26 so that the formwork body 34 causes the second structural part 3 to be positioned on the thermally insulating element 1 . The length b of the support bracket 31 is preferably only slightly smaller than the distance c between the recesses 37.

the Figures 18 and 19 show an embodiment variant in which the means for transmitting transverse forces and for transmitting compressive forces are designed in accordance with the previous exemplary embodiment. The variant according to the Figures 18 and 19 differs from the previous variant in that both the tie rods 10 and the tie rods 9 are fixed to the connecting plate 11 via fastening nuts 14 . In the exemplary embodiment, a washer 21 is arranged between each fastening nut 14 and the connecting plate 11 . However, the discs 21 can also be omitted.

the Figures 20 to 25 show different design variants for elements for compressive force introduction in the first part of the building 2. In the embodiment according to Figures 20 and 21 the compressive force is introduced via struts 19. In the exemplary embodiment according to FIG Figures 22 and 23 a thrust bearing 41 is provided for transmitting the thrust force. The width m of the thrust bearing 41 measured in the longitudinal direction 28 is not constant in the transverse direction 29, but increases from the support angle 17 in the direction of the first structural part 2. This increases the surface area for the introduction of compressive forces in the first structural part 3. In the exemplary embodiment, the thrust bearing protrudes 41 via the insulating body 5 into the first building part 2. However, it can also be provided that the thrust bearing 41 ends on the first longitudinal side 6 of the insulating body 5 and rests here on the concrete of the second building part 2 in order to introduce compressive forces into the second building part 2. As 22 shows, the thrust bearing 41 runs at a distance p, measured in the vertical direction 30, from the underside 8 of the insulating body 5. The thrust bearing 41 advantageously extends over a central region of the height of the support bracket 17. How 23 shows, the thrust bearing 41 is located approximately centrally in the longitudinal direction 28 on the rear side 54 of the support bracket 17 . The thrust bearing 41 supports the support bracket 17 in a central area between its legs 18 . Because the width m of the thrust bearing 41 increases towards the first structural part 2, a sufficiently large area of the concrete of the first structural part 2 can be activated for force application. The second part of the structure usually consists of concrete, the strength of which is higher than the strength of the concrete of the first part of the structure. The first structural part 2 can be made of in-situ concrete, for example, and the second structural part 3 in the precast plant. As a result, a smaller area of the thrust bearing 41 can be provided for the force transmission on the second structural part 3 than on the first structural part 2.

In the embodiment according to the Figures 24 and 25 anchors 42 are provided for the transmission of compressive force, each of which has a widened head 43 . In the exemplary embodiment, two anchors 42 are provided. The anchors 42 are comparatively short, so that the arrangement is also suitable for installation in a first building part 2 with a shallow depth in this area.

26 shows an embodiment variant in which the second tension rods 10 protrude through the insulating body 5 . The insulating body 5 is divided in the embodiment. A first part 52 of the insulating body 5 is held on the first part 2 of the structure, and a second part 53 of the insulating body is held on the second part 3 of the structure. In the exemplary embodiment, the first pressure rods 19 and the transverse force rods 16 protrude through the first part 52 of the insulating body 5. The second part 53 of the insulating body 5 protrudes second tension rods 10. A one-part or multi-part design of the insulating body 5 and/or a different arrangement of the parts of the insulating body 5 can also be advantageous. The support angle 17 is arranged outside of the insulating body 5 . When viewed in the longitudinal direction 28, the support bracket 17 and the insulating body 5 are next to one another and do not overlap.

The first tension rods 9 are welded to the connecting plate 11 in the exemplary embodiment, but can also be fixed to the connecting plate 11 by screws. The connecting plate 11 is in contact with the first longitudinal side 6 of the insulating body 5 . Adjacent to the connecting plate 11 the first structural part 2 has recesses 15 . The connecting plate 11 has openings for the second tension rods 10 through which these are inserted into the receptacle 15 and secured there via fastening nuts 14 ( 2 ) can be screwed.

In the embodiment after 27 the support bracket 17 is arranged in the insulating body 5 , preferably in a corresponding receptacle of the insulating body 5 . The second structural part 3 has an end face 49 which faces the insulating body 5 . In the exemplary embodiment, the second structural part 3 bears on the end face 49 27 over the end face 49 in the insulating body 5 projecting support 48, which can consist, for example, of concrete, in particular of ultra-high-strength concrete, or of metal. The support 48 can be anchored in a suitable manner in the second structural part 3, for example via reinforcement elements that are not shown. If the second structural part 3 is installed in the first structural part 2, the support 48 is positioned in the support bracket 17 and the second tension rods 10 are pushed through corresponding openings in the connecting plate 11 into recesses 15 in the first structural part 2 and screwed there.

The embodiments according to Figures 26 and 27 show building parts with increased thickness. The transverse force bars 16 do not run in the first part 2 of the structure here at the level of the first tension rods 9, but at a distance from them in the vertical direction 30.

Further advantageous embodiments result from any combination of the exemplary embodiments with one another.
